Problems solved by technology

So far, there is no known method that can prevent the fatigue vibration in four directions of the split wire of the overhead transmission line, namely: the breeze vibration in the vertical direction, the sub-gap vibration in the horizontal and horizontal directions, the along-line vibration in the along-line direction, and the galloping in the transverse torsional direction.

Embodiment 1

[0032] Embodiment 1: refer to Figure 1-6 , The present embodiment is a four-split vibration-damping and anti-galling damping spring spacer bar, which includes a frame 2 connected to four quartered clamps 1, and the frame 2 is a four-corner double frame. The body center of the frame 2 is provided with a heavy ball 3. The structures of the four damping spring shock absorbers 4 all include a cylinder 43, and one end of the cylinder 43 is connected with a spring hook 41 rotating with a fixed axis, and a built-in cylinder 43 Stretch out the piston-type spring hook 46 of this cylinder other end, the upper end of a section of piston-type spring hook in cylinder body 43 wears positioning plate 42, wears counterweight plate 47 at its lower end, between positioning plate 42 and A spring 44 and a damping rubber sleeve 45 are arranged between the weight plates 47 , and the damping rubber sleeve 45 is sleeved on the spring 44 . The four frame corners of the frame 2 are fixedly connected ...

Embodiment 2

[0033] Embodiment 2: refer to Figure 7 , A four-split vibration-damping and anti-galling damping spring spacer bar in embodiment 2 is basically the same in structure as embodiment 1, except that the frame 2 is a four-corner single frame.

Embodiment 3

Abstract

The invention discloses an anti-vibration and anti-oscillation damping spring spacer which comprises a frame, and the frame is connected with a plurality of equant cable clamps. The anti-vibration and anti-oscillation damping spring spacer is characterized in that a body center of the frame is provided with a heavy ball, and the heavy ball is connected with the frame by at least two damping spring absorbers; and the damping spring absorber comprises a cylinder body, one end of the cylinder body is connected with a spring hook with a rotating dead axle, the inside of the cylinder body is provided with a piston spring hook protruded from the other end of the cylinder body, the upper end of a section of piston spring hook in the cylinder body is penetrably provided with a positioning plate and a counterweight plate, a spring and a damping rubber sleeve are arranged between the positioning plate and the counterweight plate, and the damping rubber sleeve is sleeved on the spring. The spacer disclosed by the invention can be split into four, six, right and twelve equal parts as required, so that the spacer can play a vibration energy decrement role in the aeolian vibration in the vertical direction of a split conductor, the subspan oscillation in the lateral horizontal direction, the fair-line vibration in the fair-line direction and the oscillation in the lateral torsion direction, thereby achieving the optimum anti-vibration and anti-oscillation effect.

Description

technical field [0001] The invention relates to the technical field of overhead power transmission lines, and relates to a vibration-reducing and anti-dancing damping spring spacer. Background technique [0002] The conductors of overhead transmission lines are affected by weather conditions such as wind, ice, and low temperature all year round. The conductors often experience fatigue vibration in four directions, namely: breeze vibration in the vertical direction, sub-gap vibration in the horizontal and horizontal directions, and vibration along the line. Vibration along the line, dancing in the horizontal torsional direction. The fatigue vibration in the above four directions of the wires will cause serious damage to the towers, wires, fittings and insulators, causing frequent tripping and power outages of the lines, endangering the safe operation of the transmission lines, and causing major economic losses. [0003] In ultra-high voltage and ultra-high voltage transmissi...
